To all it Be it known thatfi donn A. MILLER, a citizen of theUnited'Statem residing at Tarrytown, in the county of 'Westchester and,

State of New York, have invented certain new and useful Improvements in S eed-Gontrolling Mechanism for Explosiveotors, of

' which the followingis a specification. n re r My iuventio i0 motors. 1

ates to improvements in speed controlling mechanism for explosive It has primarily for its object to automaticallycontrol the proportionate mixing of .t e air and gasolene, whereby'initially the power, first, by furnishing an increased supply or quantity of air the supply of gasolene not being increased; and to provide for further increasing the motive power or force by of practice increasing the supply of gasolene to the maximum supply of air to' the motor. Generally stated nese objects are attained by the employment of certain instrumentalities effectiv for making connection between the lever of the throttle-valve of .a carbureter of the float feed type and a lever on the valve controlling the gasolene-supply to the jet or spray nozzle of the carbureter, substantially as hereinafter'more fully disclosed and specifically pointed out by the claims.

In the accompan 'ng drawing illustrating the preferred embo 'ment of my invention- Figure 1 is a side elevation thereof, an Fig. 2 is a broken sectional and side elevation of the same. Fig. 3 is a vertical section at right-angles to Fig. 1.

In carrying out. my invention, I suitably connect the bell crank lever E of the throttlevalve A of a carbureter and the lever- F of the valve B controlling the 'suppl of asolene' to the jet or s ray nozzle of sai car ureter, all

lly the construction disclosed, by means of a rod, or like means, 0 havin its upper end pivotally connected to a s ort outstanding arm e of the lever E, ap IOXlmately at a right-angle to the Iatter an having an elongated slot f inits lower end-portion receiving a in'or stud h projectin from, and

forming as idable connection wit the outer end of said asolene-valve lever F. The lever E is sub ected to the action of a preferably helical or coiled spring H, having one 'ing connected together b stud and connected to said lever and its other end suitablysecured to a fixed point, said action of spring having the effect to automatically move said lever, with the throttle-valve as to cause the latterito occupy its maximum open position. This movement of the lever controlled hiya projection or stud. i K upon} the valve-casing, standing in the path iii-the" movement 02? said lever. -The lever F has its said outed ,end initiallyor normally retained at the upper end of the slot f of the rod 0 by means of a spring 0 connected to said rod and said lever at its respective ends. Also, said lever iscontrolled or limited in its movement by two projections or stopsL, O i at the divergent ends of a quadrant N fixed with relation to the fulcrum of said lever.

n The throttle valv'e E is under the control of the engine-governor, or that of the hand, through the rod D connected to said lever and actuated from either of the latter. The" throttle-valve A has an integral arm Gr nor-* mally or initially standing perfectly vertical,

said arm and the throttle-valve lever E h e-i 2: a rod P and a spring n, the latter bein directly attached to i said lever and said ro being fixed to said: arm and to said spring, the function; of?" which will be presently apparent. said] throttle-valve arm G has extending laterallvi therefrom at its base, a projection or stud I. Hi the path of the'movement of the leverfrom the valve-casing 'isr'si and rojecting g 'adapte to control the reverse move ment of the arm G, i. e. from right to left- When the parts are in the position cated in the drawings, the throttle-valve A is in its maximum open position, so retained by:. I

the action of the springs H and neonncctini with the lever E and and G, and theg;esolene valve B is likewise in 1ts maximum openrio sition, being so held through the lever F, iiod' C and the arm 0 of the lever E, the movement i of the lever F being limited or controlled by the stop or lug (l at this time. The can bureter. is now furnishing the maximum quantity of the richest mixture. Desiring to have the same quantit of mixture, but

with less gasolene, the. eel crank lever E is now moved, by suitahl actuating the rod D,

from left to right unti said lever isbronght into contact with the stud or pro ection I upon the throttle-valve arm G. The gasd leue valve B in the meantime is also moved throu h the connection thercbetween and the throttle-valve as aforesaid, the movemerit of said gasolene valve being restricted at this time by the site L, thus providing for adjusting it for the delivery of the minimum quantit iol' gasolene. The carburetor is new sup ilying the greatest quantity of the weakest mixture. Noting the position of the lever l1, it will be seen that its further movement by any additional movement of the lever ll-l'rom left to right, will be prevented by reason of its engagement with the stop L as albresaid, yet the slot and stud. con

nection between said lovers will allow of such movement of the lever E independently of the lever l the purpose of which will appear later. The further movement of the throttlevalve A by continued pulling upon the lever E through the rod 1) will cause it, by its engagement with the stud I of the throtthvalve arm G, to move said throttle-valve to its minimum open position. The carbureter at this time supplying the smallest quantity ol" the weakest mixture. Assuming that the eai-bureter is in closed condition, the lever i at that time standing in its extreme righthand position, movement of the rod D from right to left, firstallows the throttle-valve A to open to its maximum position as determined or controlled by the stop J engaging the arm G of said valve, andfurther movement in the same direction of said rod D will allow the gasolene valve B to move to its maximum open position, as cont-rolled by the stops K and 0 engaging the levers E and F respectively, as will be apparent.

l. Apparatus of the character described, employing a carburetor having its throttlevalve provided with an actuating lever adapted to have independent movement thereof and its gasolenc jetting or spraying valve provided with an actuating lever, means effecting connection between said levers, and. means adapted to retain said gasolene spraying valve at its minimum open position and the throttle-valve at its maximum open position synchronously.

2. A carburetor having a throttle-valve provided with a lever for its actuation and ith a gasolr-ne spraying valve also nipped with an actuating lever, and a rod wlnicetion between said levers, fixed to said throttle-valve lever and having a slot and stud connection with said gasolene spraying valve lever, and means for connecting the latter lever, independently of said slot and .stud connection, to said throttle-valve lever.

an actuating lever, and a rod fixed at one end to said bell-crank lever and having a slidable connection with the gasolene valve actuating lever, a spring connection between said rod and said gasolene-valve actuating -lever, means for controlling or restricting the movement, or strokes of said lovers.

4. A carburetor having a tlHOttlG-VttlVO provided with a fixed upstandii'ig arm equipped. with a lateral stud or stop, a lever for actuating said throttle-valvc adapted to have engagement with said lateral stud or stop, means of connection between said up standing arm and said lever, stops arranged for restricting the movements of said arm and said lever as said throttle-valve is moved to its open position, a gasolene spraying valve having an actuating lever, means for limiting the movement of the latter, and means effecting yielding connection between said levers.

5. A carburetor, employing a throttlevalve provided with a fixed upstanding arm, a lever for actuating said valve, means ellecting spring-connectiori between said arm and lever, said lever having attached thereto a spring for its retention in initial position, a gasolene spraying valve, a rod-connection between said lovers, the gasolene-valve actii ating lever having a spring corniection with said rod and said rod having also a slot and stud. connection with the latter lever, and means for limiting the movements of said levers.
